Christine Poerschke commented on SOLR-14865:
--------------------------------------------
Semi-related but not quite, as per
[https://lucene.apache.org/solr/guide/8_6/config-api.html#retrieving-the-config]
the {{indexConfig}} section can be inspected but when doing so the {{metrics}}
content does not appear to be correctly reflected e.g.
{code}
<metrics>
<majorMergeDocs>16</majorMergeDocs>
<int name="majorMergeDocs">8</int>
<bool name="merge">true</bool>
<bool name="mergeDetails">false</bool>
</metrics>
{code}
solrconfig.xml content is returned as
{code}
"metrics":{
"":{},
"majorMergeDocs":8,
"merge":true,
"mergeDetails":false}
{code}
during inspection.

> Key: SOLR-14865
> URL: https://issues.apache.org/jira/browse/SOLR-14865
> Project: Solr
> Issue Type: Task
> Components: metrics
> Reporter: Christine Poerschke
> Priority: Minor
>
> The documentation – e.g.
> [https://lucene.apache.org/solr/guide/8_6/metrics-reporting.html#index-merge-metrics]
> – currently mentions that _"Basic metrics are always collected"_ but
> experimentally and from a quick look at the code – e.g.
> [https://github.com/apache/lucene-solr/blob/releases/lucene-solr/8.6.2/solr/core/src/java/org/apache/solr/update/SolrIndexWriter.java#L146]
> – it appears that a {{metrics}} element needs to be configured and that it
> needs to have either a {{merge}} or a {{mergeDetails}} element configured as
> true.
